Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cart frame provided with casters, and a cart provided with a gate-type hand-push frame body provided upright at the base of the cart frame.

Here, a shopping cart will be mainly described as an example, but the present invention is not limited to this. That is, the present invention, if provided with a bogie frame and a push frame,
It can also be applied to so-called carts such as carry carts and tray carts.

The following is a list of plastic abbreviations used in this specification.

PA ... Polyamide (nylon), PC ... Polycarbonate, PE ... Polyethylene, PP ... Polypropylene, PVC ... Polyvinyl chloride,

[0005]

2. Description of the Related Art As a shopping cart, for example, FIG.
There is a configuration shown in.

[0006] The main components are a bogie frame 4 to which a plurality of casters 2 (four in the illustrated example) are attached, and a gate-type hand-pushing frame 6 standing upright from the base of the bogie frame 4. With a configuration that includes and
A product storage basket portion 8 is formed so as to project forward from an intermediate height position of the hand pushing frame body 6. In the illustrated example, the handrail frame 6 is
The side-surface standing shape is a middle "U" shape protruding forward in the middle,
The bottom base of the product storage basket 8 is connected to the top of the V-shape.

[0007]

Recently, as a supermarket / discount shop has become a large-scale suburban store, a parking lot is becoming larger.

For this reason, an increasing number of stores allow the use of a shopping cart to carry paid products from the store to their own cars.

[0009] Along with this, the shopping cart may not be returned to the predetermined position and may be left in the parking lot, and at night, it is difficult to find and is troublesome to collect. An accident may occur in which a car collides with a shopping cart.

In order to prevent the occurrence of this accident, it is conceivable to apply or attach a luminous paint (fluorescent paint) or a luminous sticker to the grip or the wheel, but the grip has a very high frequency of contact with the hand and is worn. Easy to do and not practical.
Further, although the grip and the wheel are formed of PA, PC, or the like, they may be formed of a polyolefin plastic material such as PP or PE that is lightweight and has good weather resistance.

However, since the polyolefin plastic is a non-polar material, it has almost no adhesion (adhesion) with a fluorescent paint or a fluorescent seal (usually a polar material). Also in this respect, it is not practical to apply a fluorescent paint or attach a fluorescent sticker.

In view of the above, it is an object of the present invention to provide a cart having a practical fluorescent display for preventing collision with an automobile.

[0013]

The cart of the present invention solves the above problems by the following constitution.

In a cart provided with a trolley frame body provided with casters, and a gate type hand-pushed frame body erected from a base portion of the trolley frame body, each side cover or wheel portion of the wheel portion of the caster, and the cart A cart characterized in that at least a surface layer portion of a handle grip portion of a hand-push frame body is molded from plastic containing a fluorescent colorant.

[0015]

The present invention will be described below with reference to the drawings.

The same parts as those in the above-described example are designated by the same reference numerals, and the description thereof will be omitted in whole or part.

Similar to the above, the main structure is composed of a bogie frame 4 to which the casters 2 are attached, and a hand-pushing frame 6 standing upright from the base of the bogie frame 4 (see FIG. 1). .

Specifically, the structure of the caster 2 is as shown in FIG.
As shown in FIG. 2, the U-shaped caster holding frame 10 screwed to the bogie frame 4, the wheel portion 14 pivotally supported by the axle (bolts in the illustrated example) 12 on the holding frame 10, and both sides of the wheel portion 14. Side cover 1 fixed to prevent simultaneous rotation
6 is included in the configuration. A tire 18 is attached to the outer side of the wheel portion 14 and is attached to the inner side by a bearing 20 (see FIG. 2).

Further, as shown in FIG. 3, the handle grip portion 22 is composed of a grip body 28 which is screwed to both upper ends of the hand-pushing frame body 24 via end caps 26.

Here, in this embodiment, at least the surface layer portions of the side covers 16 and the handle grip portions 22 of each wheel portion 14 are molded of fluorescent colored plastic.

For example, the side cover 16 and the end cap 26 of the handle grip portion 22 are made of PC, PP or the like containing a fluorescent pigment, and the grip body 28 is a steel pipe 2.
8a is covered with a heat-shrinkable tube 28b made of PVC or PE containing a fluorescent pigment.

If the side cover 16 is not provided in the above description, the wheel 14 is molded from fluorescent pigment-containing PA, PP or the like as described above.

Further, the handle grip portion to which the present invention is applied is not limited to those shown in FIGS.

For example, the present invention can be applied to the handle grip 22A having the structure shown in FIG.

The hand-pushing frame body 24A is formed by bending one steel pipe 24a including the grip portion, and is formed with a plastic handle cover 30 divided into two. Of course, the handle cover 30 is also a PC containing a fluorescent pigment,
Mold with PP or the like. A front bulge convex portion 30a for coupling and a receiving concave portion 30b are formed at corresponding positions on the split edge of the handle cover 30.

The fluorescent colorant may be a fluorescent dye, but usually a fluorescent pigment is used. For example, as the inorganic fluorescent pigment, oxides such as Ca, Ba, Mg, Zn and Cd, sulfides, silicates, phosphates, tungstates and the like are main components, and 1 to 0.01 % Mn, A
g, Cn, Sb, Pb, etc. are added as activators,
Some of them are produced by firing at 0 to 130 ° C. for 30 minutes to several hours and further mixing with a small amount of radioactive substance. Further, as an organic fluorescent pigment, "Lumogen L Yellow" (German IG.
Farbenindustrie. A. G. Manufactured by Kyoritsu Shuppan Co., Ltd., Showa 56
Issued P.Y. 298).

[0027]

Since the cart of the present invention has the above-described structure, the caster portion and the handle grip portion emit fluorescent display at night. Therefore, the entire plane size and height of the cart can be recognized by a viewer from a distance without lighting. Therefore, even if the shopping cart is left in the parking lot, it is easy to find it when it is collected at a predetermined position, and the cart collection operation is easy, and there is no risk of collision with an automobile or the like.

Further, since the fluorescent display is performed with the fluorescent colorant mixed in the plastic material, there is no fear that the fluorescent paint is worn or the fluorescent seal is peeled off.
It is practical because the fluorescent display function does not disappear early.
